To all wwm t concern s Be it known `that we.V lvl-,intimi ji. Viliiunw LiN and ldicifmnn "Y uam, citizens or the United States, ri in the city et Si; Louis and State et lil i euri, have invenird a certain new and i i e'nl Combined Eyff Dropper, t'iyrincn anti if lilediciue-leider, oit which the tollowino' 4 i specification.

Oui' invention reljaites to improvements in syringes and has for its objects lo provide a combined device et the class mentioned which may be successfully used as an eyedropper, iypoderniic syringe, or ordinary syringe and medicine holder.

' 1With the above and other objects in view which will appear hereinafter, the invention consists inthe novel arrangement and coinbiiiation of parts, Clearly illustrated in the drawing, described in the following specilication and finally pointed out in the claims hereto appended.

Referring to the acconnianying drawings forming a part of this specification wherein like characters off reiereiice denote similar parts throughout the several views:

Figure 1, is a vertical sectional'view oiL a device constructed and. assembled in accordance with our invention.

Fig. 2, is a similar view with the removable medicament holder removed from the combined piston barrel and liquid medicine holder.

Fig. 3, is a vertical sectional view of the, device, with the piston barrel shown in an outer extended position, and with the removable medicine holder removed.

Fig, 4, is a vertical sectional view oi' the device, with the removable medicine holder lshown within the'piston barrel7 and a hypoderinicneedle attached showing the device in lreadiness for use as a hypodermic syringe. In carrying out thehun of our invention,

vwe employ en outer barrel 1 having the upper open end 2. The upper edge ot the barrel`1 vis provided with a circumferential lange. The lower end oit the barrel 1 is provided with a Contracted oi' reduced' portion in the forni of a nozzle 4 having the central opening;4 as passage 5. The nozzle i is provided with a removable closure or cap 6 made, preferably, from sott rubber so that it will readily close any puncture thereof caused by the insertion or passage therethrough of a hypodermic needle 7, one of Application filed 'November 13, 1317.

Serial No. 202,840.

which needles is shown as passed through the cap G iu Fig'. al.

second or'iiiner barrel S is employed. which acts both as a pistonbarrelv and: ay liquid medicine holder,

which is provided with a suitable reinov able stopper 10. The upper edge of the barrel 8 'provided with a eireuniferential)Y flange 10", and vis further provided with a texible resilient washer 11 which is adapted- 65 to be grasped by the fingers for pulling the inner barrel 8 into any desired extended" position. The washer 11 is of a greater di- Y aineter than the inner barrel flange 10. The

lower end oi. the inner barrel 8 has a con- 70 tracted neck portion 12 provided with 21;

liquid passage or opening 13.

Surrounding 12 of the` inner barrel 8 is a iubberoiston ring- 1l, and surrounding the remain er or 75 upper portion of tlie neck 12 is a ypiston ring termed by wrappings of asbestos cord 15.

llt will be observed that the ring lljand 00rd 15 term a continuous cylindrical `packinni ring' ot' considerable length thereby pro- 80 riding a packing or piston ring which cannot leak, and one which keeps the inner bar.- rel parallel with the outer barrel in its re/ ciprocating movements, thereby preventing a walobly movement of the inner barrel -8 85 while being` reciprocated, as is manifest.

The medical tablet holder consists ofa remo'able bottle or barrel 16 having a1;

closed lower end and an open upperA end the latter adapted to receive a suitable stopper 17, as clearly shown in Figs. 1 and 4l This removable holder 16 is adapted to retain tablets or powder, or medicament in either ai drv or liquid state, as desired.`

The opertion ot the device is as follows:

lt will be observed, that-when the vdevice is used as an' eye-dropper, that the liquid ma) be carried within the inner barrel 8, as clearly showintcr instance, in Fig. 2. When it is desired to transfer a portion of the ,he inner barrel S has an upper openend 60 the lower half of the rneck ierred, the closure or cap 6,' of the nozzle 4, 105

` cork ir stopper 10 is removed, the barrel 8 charged from the nozzle 4 in drops as fast or as slow as may be desired. 'Ijhe drops are regulated by the pressure applied to the innerbarrel 8, as is manifest. If, after-.the treatment, there'is any liquid remaining in the outer barrel 1, it may be retransferred to the'inner barrel 8 by replacing the closure 6 on4 nozzle 4, .removingstopper- 10, from barrel 8, and then forcing the barrel back into its closed or innermost position 1n the outer barrel 1, as is'manifest. Q 'At no time after the outer-barrel 1 1s -em` ty, evenfthough the cap 6 is removed,

[wil the contents run. from the li uid medicine holder 8 into the barrel 1, un ess an extended movement is imparted to the barrel 8; Itwill thus be seen that, where expensive medicine 'is contained in barrel 8, that inner barrel 8 and a tabletdropped into the li uid. These operations are, preferably,

a apted to be performed while the inner barrelg8 is in a closed position.d While the i is withdrawn or extended a suitable distance l thereby causing the liquid, or part of it jing theclosure or cap ,6 from the nozzle 4,

within' the barrel 8' to be transferred into vthe outer' barrel 1, as clearly shown in Fig.

-3. After the inner barrel 8 has been eir-I tended and the desiredl amount of liquid transferred to .the outer barrel, the stopper l .10 is a lain inserted into the upper open end 4o of the arrel' 8, and the closure or cap 6 is -then removed from the nozzle 4, of the outer barrel v1. After these operations, the device-is ready for an injection, as is manifest.

It will be observed, ythat the syringe may be vfilled in the usual Way, by merely'removand without removing the medicine or .tablet holder 16 by merely withdrawing-0r 'extending the inner barrel 8, as is manifest.

-. When used as a hypodermic syringe, a .hypodermic -needle 7 is passed through the closure or ca 6 and through the opening or passage 5 o the'nozzle 4 into 'the interior o f theouter barrel 1. `The medicament in liquid form rfor ax hypodermic injection' is placed intothe louter barrel 1 and the medicine holder' -of bottle 16 is carried within the inner or lpiston barrel S'thereby permit- -n' ting greater force to' be 'applied to the dis- '60 charge-of the liquid through the needle 7, as is manifest. f

The many. advantages ofthe-l herein described invention will readily suggest them- .selves tothose skilled in the art to which it j'anpertams.

From the foregoing description, it will be seen that we provide a device which is simple and cheap in construction, one that may be easily and readily charged with the desired medicated solution of deinite strength,

redetermined quantity, and always ready or use when desired.

What we claim is:
